摘　　要：针对煤矿井下复合材料路面结构的应用情况,通过对玻纤增强复合材料的加工工艺进行对比,选择适用于煤矿巷道自动化铺底模块加工的拉挤成型工艺,设计了铺底模块的几何结构并建立其有限元仿真模型,模拟铺底模块在应用过程中的受碾压工作状态,分析并对比铺底模块在使用3种不同规格螺栓时的应力状态、在3个不同位置受碾压时危险区域的应力和应变分布、变化趋势以及失效风险,得到合理的板材厚度和连接件尺寸选型,提高了研发效率和可靠性。According to the application status of composite road surface in underground colliery,after the comparison of manufacturing technology of glass fiber reinforced composite,the pultrusion forming technology suitable for manufacturing automatic mat module in colliery roadway was identified.The geometric structure of the mat module was designed,and its finite element simulation model was established to simulate the rolled status of the mat modules in service.After the stress status of the mat module with three sizes of bolt,the stress and strain distribution in risk zone at three position,variation tendency and failure risk being analyzed and compared,reasonable board thickness and size of connecting parts were obtained,which greatly improved the research and development efficiency and reliability.
